The word modem is short for modulator-demodulator which is essentially what it does. A computer moves data around on parallel wires by applying one or another voltage to each wire (representing 0's and 1's) and the voltage is read at the other end of the wires.This is digital communication.odem is short for Modulator/Demodulator. A modem receives analog signals from the cable provider (in this case a cable modem) and modulates the carrier signal to encode it into a digital signal readable by your router or NIC.
